* nozomi: Fix mutex handlingAlan Cox2010-03-021-22/+12
| | | | | | | | | | | The original author didn't realise the kernel lock was a drop while sleep lock so did clever (and wrong) things to work around the non need to avoid deadlocks.

* nozomi: Add tty_port usageAlan Cox2010-03-021-47/+68
| | | | | | | | | | | | | | | | The Nozomi tty handling is very broken on the open/close side (See http://bugzilla.kernel.org/show_bug.cgi?id=13024 for one example). In particular it marks the tty as closed on the first close() not on the last. Most of the logic is pretty solid except for the open/close path so switch to the tty_port helpers and let them do all the heavy lifting. This is also fixes all the POSIX behaviour violations in the open/close paths. Begin by adding the tty port usage Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Char: synclink, remove unnecessary checksJiri Slaby2010-03-021-2/+2
| | | | | | | | | | | | | | | Stanse found a potential null dereference in mgsl_put_char and mgsl_write. There is a check for tty being NULL, but it is dereferenced earlier. Actually, tty cannot be NULL in .write and .put_char, so remove the tests.

* serial: synclink_gt: dropped transmit data bugfixPaul Fulghum2010-03-021-81/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix transmit bug that could drop send data if write() called close to serial transmitter going idle after sending previous data. Bug is caused by incorrect use of device information member tx_count. Driver originally processed one data block (write call) at a time, waiting for transmit idle before sending more. tx_count recorded how much data was loaded in DMA buffers on write(), and was cleared on send completion. tx_count use was overloaded to record accumulated data from put_char() callback when transmitter was idle. A bug was introduced when transmit code was reworked to allow multiple blocks of data in the tx DMA buffers which keeps transmitter from going idle between blocks. tx_count was set to size of last block loaded, cleared when tx went idle, and monitored to know when to restart transmitter without proper synchronization. tx_count could be cleared when unsent data remained in DMA buffers and transmitter required restarting, effectively dropping unsent data. Solution: 1. tx_count now used only to track accumulated data from put_char 2. DMA buffer state tracked by direct inspection of descriptors with spinlock synchronization 3. consolidate these tasks in tx_load() : a. check for available buffer space b. load buffers c. restart DMA and or serial transmitter as needed These steps were previously duplicated in multiple places, sometimes incompletely. 4. fix use of tx_count as active transmit indicator, instead using tx_active which is meant for that purpose Signed-off-by: Paul Fulghum <paulkf@microgate.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| * Input: Mac button emulation - implement as an input filterDmitry Torokhov2010-01-301-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementation of Mac mouse button emulation plugs into legacy keyboard driver, converts certain keys into button events on a separate device, and suppresses the real events from reaching tty. This worked well enough until user space started using evdev which was completely unaware of this arrangement and kept sending original key presses to its users. Change the implementation to use newly added input filter framework so that original key presses are not transmitted to any handlers. As a bonus remove SYSCTL dependencies from the code and use Kconfig instead; also do not create the emulated mouse device until user activates emulation. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

If the host supports this feature as well, the config space has the number of ports defined for that device. New ports are spawned according to this information. The config space also has the maximum number of ports that can be spawned for a particular device. This is useful in initializing the appropriate number of virtqueues in advance, as ports might be hot-plugged in later. Using this feature, generic ports can be created which are not tied to hvc consoles. We also open up a private channel between the host and the guest via which some "control" messages are exchanged for the ports, like whether the port being spawned is a console port, resizing the console window, etc. Next commits will add support for hotplugging and presenting char devices in /dev/ for bi-directional guest-host communication.
